Answer:
Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease:
Airway diseases -- These diseases affect the tubes (airways) that carry oxygen and other gases into and out of the lungs. They usually cause a narrowing or blockage of the airways. Airway diseases include asthma, COPD and bronchiectasis. People with airway diseases often say they feel as if they're "trying to breathe out through a straw."
Lung tissue diseases -- These diseases affect the structure of the lung tissue. Scarring or inflammation of the tissue makes the lungs unable to expand fully (restrictive lung disease). This makes it hard for the lungs to take in oxygen and release carbon dioxide. People with this type of lung disorder often say they feel as if they are "wearing a too-tight sweater or vest." As a result, they can't breathe deeply. Pulmonary fibrosis and sarcoidosis are examples of lung tissue disease.
Lung circulation diseases -- These diseases affect the blood vessels in the lungs. They are caused by clotting, scarring, or inflammation of the blood vessels. They affect the ability of the lungs to take up oxygen and release carbon dioxide. These diseases may also affect heart function. An example of a lung circulation disease is pulmonary hypertension. People with these conditions often feel very short of breath when they exert themselves.

Explanation:
When a proto-oncogene changes then it becomes a "bad" gene called an oncogene that can enhance activated forever when it is not presumed to be. When this occurs, this will grow the cell out of control, yet if the initial trigger is removed his unnatural growth normally produces a mass, thus the tumor is formed. Benign tumors comprise osteophytes, uterine fibroids, and melanocytic nevi which are restricted and limited and do not convert into cancer but Potentially malignant neoplasms constitute carcinoma in situ. which are limited, do not invade and finish but in the future, they may convert into cancer.
